Question

(task3.m) The flow over a circular cylinder (nonlifting flow): pressure coefficient (the surface
pressure distribution)
As "task3.m" script runs from "P2amain.m" script, it must output the following plot (no user inputs
required):
The "pressure coefficient" plot on the surface of the cylinder (the surface pressure distribution for both
upper & lower surfaces in a single figure). Use a non-dimensional coordinate parameter x/R (in the range
of -1 < x/R <1) for the x-coordinate of your plot. (Note) the Cp plot in aerodynamics is "negative values
in positive y coordinate direction" (rule of thumb). This will require you to modify the y axis data
direction ("flip-flop" of the y coordinate) when you perform Cp plot in MATLAB.
